Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629904, here are decompositions:

13 + 8629891 = 8629904
37 + 8629867 = 8629904
193 + 8629711 = 8629904
223 + 8629681 = 8629904
307 + 8629597 = 8629904
397 + 8629507 = 8629904
421 + 8629483 = 8629904
457 + 8629447 = 8629904

Showing the first eight; more decompositions exist.
